RELEASE-RIGGING.

To all whom it may concern:

Be it known that I, RAY F. SMITH, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Itelease-Riggings, of which the following is a specification.

It is desirable, as is well known to those skilled in the art, to construct release rigging in such a manner that the coupler head is free to move under bufling and draft strains and when the car is moving on a curve without putting any strain on the release rigging. A number of draft riggings have been constructed which provide more or less for these movements of the coupler head.

By my invention, I believe that the movements of the coupler head are taken care of in an efiicient and practical way by a simpic but desirable construction, in which the parts may be replaced without disturbing the whole structure and without heating the metal.

In the drawings, Figure 1 is a top plan view of an end sill of a car with my im proved release rigging attached thereto; Fig. 2 is a front elevation of the same.

The numeral 1 represents an end sill of i any approved pattern.

2 is a coupler of standard type having the usual locking pin 3.

The numeral 4 is a hand operated rod secured to the end sill by means of the straps 5 or in any other well-known manner. The outer end of the rodis bent to form a crank 6, which depends below the under face of the end sill in order that it may be operated without any liability of the operator becoming crushed between the cars. The inner end of the rod is bent to form a crank 7 at right angles to the crank 6.

The numeral 8 is a three-way casting comprising the arms 9, 10 and 11; the arms 9 and 10 being hollow, while the central body of the casting is hollow so that an uninterrupted bore is provided. The arm 11 is also tubular and is adapted to receive the end of Specification of Letters Patent.

Serial No. 629,227.

the arm 12 of the crank 7 said arm being secured in the arm 11 by means of a cotter or other suitable pin 13.

The numeral la is a pin lifting lever, the inner end of which is reduced in diameter and bent to form an elongated eye or hook 15, in which the upper end of the locking pin is secured. The elongation of the eye provides for sidewise motion of the coupler head, as will readily be understood. The pin lever is provided with an arm 16 at right angles thereto constructed to pass through the openings in the casting 8 and its arms 9 and 10, whereby it is given a long bearing. It is secured in the casting by means of a cotter or other pin 17. As will be seen, the pin lever 14: is mounted in the casting in such a manner that it may have a swinging motion relative thereto, whereby it may follow the coupler head in its forward and backward movement in draft and bufling without subjecting the release rigging to any strain. The free swinging mounting of the pin lever 11 prevents any binding or undue friction of the rod 1 in the straps 5. Of course, it is obvious that in operating the rigging to unlock the locking pin, the rod 4: is revolved by the crank 6.

IVhat I claim is 2-- In an uncoupling device for operating the locking pin of a car coupler, the combination with a longitudinally rotatable lever having a plurality of crank arms, one of said arms extending forwardly from the car upon which the lever is mounted, a three way casting keyed to said forwardly extending arm, two of said ways being in alinement with each other and constituting an elongated bearing, a lever engaging the locking pin and provided wlth a depending arm adapted to be pivotally mounted in said elongated hearing.

In testimony whereof I affix my signature in presence of two witnesses.

RAY F. SMITH.
